DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 328,037, dated October13, 1885.

Application filed May 8, 1885. Serial No. 164,784.

To all whom, it may concern:

Be it known that I, MAURICE KANE, of Chicago, Cook county, Illinois,have invented new and useful Improvements in Draft-Equalizers, whichimprovements are fully set forth in the following specification andaccompanying drawings, in which Figure 1 is a perspective view ofequalizer attached to a pole. Fig. 2 is a top view of equalizer-plate.Fig. 3 is a front view of the same.

The object of my invention is to furnish a draft-equalizer for three ormore horses, to be used in connection with apole, and connected directlythereto, and provided with an adjustable stop, so that when used onharvestingmachines its movement can be controlled, so that thesingletree will not come in contact with the reel.

My invention consists, further, in arranging the two-horse double-treeso that it can be used on equalizer'plate in place of triple-tree, whendesirable.

My invention consists, further, of a threehorse equalizer which can beconnected directly to the .pole, dispensing with draft-rods, chains, andsupports usually employed on equalizers.

In the drawings, A is a section of the pole.

B is the long arm of the triplet-rec, which is pivoted at b, with slotat b.

C is the short arm of the same, with fulcrum atf, and connected to B bymeans of stud I), being bolted rigid to C, and being free to move inslot 12 D is double-tree, with stud d, being equal in size to studf onFig. 3. This makes it interchangeable with triple-tree B, when desirableto use only two horses.

E E E are single-trees, constructed in the usual manner.

F is equalizer-plate, with pivotstud f, fulcrum-stud f, and stationarystop f, in connection with adjustable piece f which, when not in use, isplaced in position as shown by dotted lines; also stud f, to whichpole-brace f is connected.

(N0 model.)

I would further describe the working of the adjustable stop f. This stophas a square projection at its upper end. The height of this projectionis equal to the width of f 3 across its face where itcomes in contactwith and serves as a stop for B. This projection fits a recess instationary stop f", the object being to prevent f from moving sidewisewhen in a position to serve as a stop, and to prevent it from droppingdown when not in use. This position is shown by dotted lines. Thethickness of f below the square projection is determined by the amountof movement required for equalizer B. I do not wish to be confined tothis manner of constructing an adjustable stop for this purpose, asthere are various ways in which this can be done.

It will be seen from the foregoing that, f being the fulcrum for C, thedraft will be equally divided. Although the spaces between b, b, and fmay not be geometrically correct on the drawing, it is near enough toillustrate the principle.

The operation of my device is not confined to connecting C to B in themanner shown on the drawings. It is obvious that if C were placedforward or back of B and connected thereto, with fulcrum in the samerelative position, the result would be the same. Also, the slot 1) mightbe at b, or on C at fulcrum f; or stud b might be connected rigidly toB,

and C be slotted for the stud to move in.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

1. The long arm B, with slotted hole, in combination with short arm C,with fulcrum, as shown and described.

2. The plate F, in combination with studs f andf, and adjustable stop fand studf, as shown and described.

3. An adjustable stop, either in combina tion with or separate fromplate F.
